Answer:
360 degrees
Step-by-step explanation:
Its Easy Geometry
21,45,6
21=3*7
45=3*3*5
6=3*2
LCM= 3*3*7*5*2
LCM=630
2 / 3 ( y + 57 ) = 178
2( y + 57 ) / 3 = 178
2*y + 2 * 57 / 3 = 178
2y + 114 / 3 = 178
3*(2 y + 114 ) / 3 * ( 178)
2 y + 114 = 534
2y = 534 - 114
2 y = 420
y = 420 / 2
y = 210
hope this helps!
